As shown in FIGS. 1 and 2, the mounting table (1) is capable of mounting a magazine space, and this magazine space is capable of storing a plurality of plate-shaped articles in the vertical direction.

One end of the fixed path (9) is formed at a handling area 6η on the outside, and a transfer device (not shown) for transferring the magazine group is provided between the handling area 6η and the mounting platform. .

This transfer device consists of forks, conveyors, etc.

Next, the warehousing operation in the above embodiment will be explained.

With the delivery device mo* facing the handling and lifting load and stopped, the magazine value 4 at the handling place η is transferred onto the mounting table (a) by the transfer device. A large number of articles are stored in this magazine with a part of the rotary table a'IJ side exposed. In this state, the traveling body (to) is run, and the elevating platform (to) is raised and lowered to face the rotary table aη to the intended compartment storage space (2).

At this time, the rotary table Q7) is stopped rotating with its concave portion) directed toward the mounting table (E). Further, in the loading/unloading device OI, the fork (to) is in the lowered position, and the clamping plates (89A) (89B) are in positions spaced apart from each other. In this state, first, the screw shaft υ is rotated via the motor, and the box frame C9 is advanced via the connecting plate (2) by movement of the nut body (0) and guidance by the guide rail ().

As a result, the fork (2) is located below the target article and enters the magazine t5i. Further, both clamping plates r89A) (89B) are located outside the side surface of the exposed part on the article side. Next, the fork action is raised and both clamping plates (89A) (89B) are moved closer to each other. By these actions, the target goods place is lifted by the fork (to), and the exposed end is held by the clamping plate (89).
A) ('19B). In this embodiment, two articles are simultaneously lifted and held together. Furthermore, when the article is clamped, the positioning bins (40A) (40B>) fit into the recesses (56a) of the article, so that the article is positioned.
) and the recess (56a) may be omitted.

In the above-mentioned lifting and clamping state, the box frame (to) is moved in and out, and the article is thereby drawn onto the rotating table lumen η as shown in FIG. Next, rotate the rotary table Qη with the vertical axis O
The article is rotated 90 degrees around f3 to face the intended compartment storage space (2).

From this state, the stop position confirmation device is activated.

That is, the cylinder devices are contracted and the push/pull rod (2) is moved to protrude via the piston rod I5D, the holder b4, the sliding cylinder body (1), the spring (2), and the stopper body. When the tip engaging pin (6) of the protruding push/pull rod (2) engages with the engaged hole (6) as shown by the imaginary line in FIG. 4, the abnormality detection device (fi) does not operate.

After the cylinder device reaches its contraction limit, it immediately shifts to an extension motion, and the push/pull rod is housed in the rotary table αη. As described above, when the abnormality detection device does not operate, the loading/unloading device o1 performs the loading/unloading operation. That is, the box frame () is moved forward by the above-mentioned operation, and the article (-) is thrust into the intended compartment storage space (2) via the fork (to) and the clamping plates (39A) (89B). Next, the fork (to) is lowered and the clamping plate (39
The AJ (89B) is moved apart to support and release the article while passing it between the pair of left and right receiving plates (6). Thereafter, the loading/unloading device α0 is retired. When the above-mentioned stop position confirmation device (Foundation) is activated, and the lifting platform (to) is stopped with a slight vertical deviation from the predetermined position, the engagement pin (to which the protruding movement occurs)
6) comes into contact with the front surface of the partition plate (4) without engaging with the engaged hole θυ, and further protrusion is prevented. At this time, the stopper body) stops facing the abnormality detection device, and an abnormality is detected. The remaining contraction movement of the cylinder device after the protrusion is prevented is caused by the sliding cylinder against the spring.
is absorbed by movement. After an abnormality is detected and the engagement bin □□□ is moved in and out, the loading/unloading device θ
The elevator is not operated, and the lifting platform (to) is moved up and down again to adjust the vertical position. After stopping, the stop position confirmation device is operated again to project the engagement pin (A) and confirm the stop position. Such repeated confirmation actions are performed many times until the abnormality detection device stops operating.

As mentioned above, after the article φQ is stored, the next storage is performed, and at that time the rotary table αη is rotated by 9011f around the vertical axis QQ, and the loading/unloading device θ
After the article is placed opposite the magazine opening, the article is taken out from the magazine opening by the above-described operation.

In addition, the delivery device GO uses the rotary table Q force to move the rotary table Q force to the next purpose compartment storage space ( 2). Thereafter, the desired warehousing operation is performed using the same action as described above.

When the magazine opening is empty, the receiving device QO is returned to the handling area 9η, the empty magazine is unloaded, and a new magazine opening is loaded.

By carrying out the opposite action to that described above, the target steel article can be taken out from the divided storage space (2) and placed in an empty magazine, thereby making it possible to take the goods out of the warehouse.

Effects of the Invention According to the present invention as described above, after the lifting platform is stopped in correspondence with the target compartment storage space, the engaging bin is projected toward the corresponding engaged hole, and at that time, the engaging bin is not engaged. When the stop position confirming device confirms that the bin is engaged with the engaged hole, the intended loading/unloading operation can be performed by operating the loading/unloading tool. Further, when the engagement bin does not engage with the non-engagement hole and collides with a shelf frame or the like, the stop position is abnormal and the stop position confirmation device does not confirm the stop position.

In this case, after raising and lowering the platform again and stopping it,
As described above, by moving the engagement pin in a protruding manner, the stop position can be confirmed again. As described above, according to the present invention, it is possible to mechanically check the stop position of the lifting platform before carrying out loading/unloading operations using the loading/unloading device. Even in warehouse facilities where compartmentalized storage spaces are formed at short pitches in the vertical direction and the allowable space for loading and unloading devices to operate in the vertical direction is narrow, storage shelves, delivery devices, and especially expensive items can be prevented from being damaged. , you can always carry out reliable loading and unloading operations.
